Crossmark

Crossmark gives readers quick and easy access to the current status of a piece of content. With one click, you can see if content has been updated, corrected or retracted and access valuable additional metadata provided by the publisher.

Benefits

Researchers and librarians can easily see the changes to the content they are reading, find out who funded the research, what licenses apply to the content and more.

Anyone can access the Crossmark metadata through our REST API, providing a myriad of opportunities for integration with other systems and analysis of changes to the scholarly record.

How it works

Publishers place the Crossmark button close to the title of a piece of content on their web pages and in PDFs, and commit to informing us if there is an update such as a correction or retraction. They also send additional metadata such as authors’ ORCIDs and the funders behind the research.

When a reader clicks on the button a pop-up box appears that headlines the current status of the content: up-to-date, updates available, or retracted, and also displays all of the additional information. Watch the video below to find out more:
